Synthesis of a Novel Class of Macrocyclic Compounds Containing 1,3,4-Thiadiazole Rings as Subunits
摘要:
The synthesis and characterization of 12 new macrocycles containing two, four, or six 1,3,4-thiadiazole rings as subunits are described. The general methodology used is based on the nontemplated reaction of bis(4-methyl-5-(methylthio)-1,3,4-thiadiazolium) diperchlorates with alpha,omega-diamino compounds. Complexation properties of macrocycles 4a-4c and 4e toward Ag+ are also reported.
